Claims

[Scope of utility model registration request]

It has two ropes that are suspended directly below the drum and are stretched so as to be able to raise and lower the two upper sheaves of the spreader provided at one end of the spreader, and are provided in a horizontal position orthogonal to the drum. It has two ropes stretched so as to be capable of hoisting up and lowering two upper sheaves of the spreader provided at the other end of the above-mentioned spreader through two oscillating sheaves, and furthermore, A container crane hoisting device in which the position of the support point of each rope is adjustable so that the directions of the resultant force of each two ropes at both ends can be positioned relative to each other.
